DRAW-BAR.

Specification of Letters Patent.

f atcn'ted Mar. 1, 1910.

Application led June 28, 1909. Serial No. 505,286.

To all whom it may concern:

t Be it known that l, JACOB E. TnoUP, a citizen of the United States,residing at Perry, in the county of Dallas and State of Iowa, haveinvented a new and useful Draw- Bar, of which the following is aspecificatlon.

The object of this invention is to provide an improved construction fordraw-bars for railway cars.

A further object of this invention is to provide improved means forconnecting a draw-bar yieldingly to draft timbers of a railway car.

My invention consists in the construction, arrangement and combinationof elements hereinafter set forth, pointed out in my claims andillustrated by the accompanying drawing, in which- Figure 1 is a planillustrating the construction and mounting of my improved draw-barrelative to draft timbers of a car. Fig. 2 is an elevation of one sideof one of the draft timbers. Fig. 3 is a cross-section on the indicatedline 3-4 of Fig. 1 looking in one direction, and Fig. l is across-section on the same line looking in the opposite direction.

In the construction of the drawebar and its mounting as shown thenumeral 10 designates the body member and 11 an extension member adaptedto be bolted to the body member as shown and further adapted to beconnected to a draw-head or coupler (not shown) of any desired form. Thebody member 10 is mounted between draft timbers 13, 14C of a railway carand is adapted to be secured thereto in the manner about to bedescribed. .lhe body member 10 of the draw-bar is formed with a centralbore or aperture 15, which opens to the rear end thereof and extendsnearly to its forward end. The body 10 of the draw-bar is formed with aslot 16 in one side, which slot opens to the central bore 15. The bodyportion 10 of the drawbar also is formed with slots above and below andopening to the central bore 15 and on one side of the vertical slots themember 10 is rabbeted at the top and bottom to produce a bar or rib 10a.The end portions of the rabbets are beveled. A bifurcated brace 17straddles and extends across the forwardV end portion of the rib 10a. Abrace 18 extends through the forward end portion of the slot 16. Theinner end portions of the braces 17, 18 overlap and are pivotallyconnected by 'a bolt 19 extending vertically through the forward endportion of the bore 15 and through the slots above and below said bore.Beveled end portions of the braces 17, 18 extend within metal boxes orsockets 20, Q1 embedded in and fixed to opposite faces of the drafttimbers 13, 14 and normally extend obliquely forward from the bolt 1S).A presser plate 9.2 is mounted in contact with the rear margins of theinner end portions of the braces 17, 18. One end portion of the presser'plate 22 is forked and straddles the rib 10a while the other end portionof said presser plate is reduced in width relative to the fork andextends through the slot 10. A bifurcated brace Q3 straddles and extendsacross the rear end portion of the rib 10a. A brace 24 extends throughthe rear end portion of the slot 16. The inner end portions of thebraces 9.3, 24 overlap and are pivotally connected by a bolt 25extending vertically through the rear end portion of the bore 15 andthrough the slots above and below said bore. Beveled end portions of thebraces Q3, 24. extend within metal. boxes or sockets 2G, 27 embedded inand fixed to opposite faces of the draft timbers 13, 14 at the rear ofthe boxes 20, 21 and normally extend obliquely rearward from the boltQ5. A presser plate 28 is mounted in contact with the forward margins ofthe inner end portions of the braces 23, 24;. One end portion of thepresser plate 28 is forked and straddles the rib 10a while the other endportion of said presser plate is reduced in width relative to the forkand extends through the slot 16. V

An expansive coil spring 29 is mounted in the bore 15 and impinges atopposite ends with the presser plates 22 and Q8. ln assembling the partsthe spring 29 is inserted in the bore before the presser plate 28,braces 23, 24 and bolt 25 are placed in position, for the reason thatsaid spring is of larger diameter than the width of the slots opening tosaid bore and must be intron duced to the bore at the rear end of themember 10.

In practical use the parts are assembled as shown. Any draft on the barmembers 10, 11 is cushioned by the spring 29 and is transmittedlaterally on inclined planes through the braces 17, 18 to the boxes orsockets 20, 21 and draft timbers 13, 14. Any pressure or impact on thebar members 10, 11 is cushioned by the spring 29 and is transmittedthrough the presser plate Q8 and baces 23, 24 laterally on inclinedplanes to the boxes or sockets 26, 27 and draft timbes 13, 14. Thedesirable amount of slack or freedom of movement of the bar members 10,11 longitudinally relative to the draft timbers 13, 14 is provided forby making the bore 15, slot 16 and rabbets on opposite sides of the bar10 of greater length than the spaces between the forward faces of theinner ends of the braces 17, 18 and the rear faces of the inner ends ofthe braces 23, 24 (Fig. 1).

I claim as my invention 1. The combination of draft timbers, a draw barmounted between said timbers, braces pivotally connected at their innerends and extending` obliquely across and arranged in pairs atV oppositeends of said draw bar, outer end portions of said braces looselyengaging said draft timbers, and yielding pressure devices interposed between the pivo-ted ends of the pairs of braces.

The combination of draft timbers, a draw bar mounted between saidtimbers and formed with a longitudinal slot, braces pivotally connectedat their inner ends and extending obliquely across said draw bar atopposite ends of said slot, outer end portions of said draw bar looselyengaging said draft timbers, and yielding pressure devices moui'ited insaid slot and interposed between the pivoted ends of the pairs ofbraces.

3. The combination of draft timbers, a draw bar mounted between saidtimbers and formed with a longitudinal bore, pairs of braces arranged atopposite ends of said bore, each pair of braces crossing said draw barand pivoted together coincident with said bore, one pair of bracesextending obliquely forward and the other pair of braces extendingobliquely rearward, outer ends of said braces loosely engaging saiddraft timbers, and yielding pressure devices interposed between theapices of the pairs of braces;

` 4t. The combination of draft timbers,

sockets therein, a draw-bar mounted between said timbers, pairs ofbraces spaced apart longitudinally ofsaid draw-bar, each pair of bracescrossing said draw-bar and pivotally connected at the center thereof,one pair of braces extending obliquely forward and the other pair ofbraces extending obliqucly rearward, presser plates between said pairsof braces, and an expansive spring between and impinging on said presserplates.

5. A draw-bar formed with a longitudinal bore opening to one end thereofand also formed with slots in its sides communicating with said bore andrabbets communicating with some of said slots, presser plates mountedtransversely of said draw-bar, each plate forked at one side and reducedin width at theother side, a cushioning spring between said presserplates and within the bore of the draw-bar, and braces carried by saiddrawbar and extending oblique-ly therefrom, said braces ,adapted to beengaged by said presser plates on one side and by the draw-bar oppositethereto,

6, A draw-bar formed with a longitudinal bore opening to'one end thereofand also formed with slots in its sides communicat ing with said boreand rabbets communicating with some of said slots, presser platesmounted transversely of said draw-bar, each plate forked at one side andreduced in width at the other side, a cushioning spring between saidpresser plates and within the bore of the draw-bar, and braces carriedby said draw-bar and extending obliquely therefrom, said braces adaptedto be engaged by said presser plates on one side and by the draw-baropposite thereto, some of said braces forked and others of said bracesreduced in width and pivotally connected to the forked ends of the firstbraces.
